Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport container for transporting a fluid in a housed state.

[0002]

2. Description of the Related Art Expanded polystyrene (so-called expanded polystyrene: EPS) is used as a packaging for home electric appliances and audio-visual (AV) equipment, or as a food tray for fish and meat.
Are used in large quantities. This type of expanded polystyrene has characteristics such as excellent impact buffering properties, easy processing into an arbitrary shape, and low price and good appearance. However, when incinerated as waste, expanded polystyrene generates high heat, shortens the life of the incinerator, produces a strong odor, and does not decompose in the soil when discarded. Have a point.

[0003] As an alternative to expanded polystyrene, pulp mold materials produced by recycling milk packs, cardboard, newsprint and the like have begun to be partially used. However, foamed polystyrene exhibits excellent shock-absorbing properties due to its own elasticity, whereas pulp mold material provides buffering properties by processing paper into an uneven shape, so its strength and cushioning properties are reduced. Has a limit and the variation in characteristics is large. Therefore, for general packaging products, especially large products such as refrigerators, washing machines, and televisions, for the time being, expanded polystyrene must be mainly used as a packaging material. Therefore, attempts have been made to collect and recycle the expanded polystyrene molded article.

However, the recovery rate of the expanded polystyrene molded article is extremely low at present compared to paper. This is due to the fact that used paper, such as newspapers and magazines, has many collection companies and the price of paper is stable,
As is apparent from the fact that foamed polystyrene has a small apparent specific gravity of about 0.02, the volume is extremely large for its weight, and there are no storage places or collection costs. The recovery of the compact is extremely low. Equipment that melts and forms blocks of expanded polystyrene with heat has been introduced in some factories, but such expanded polystyrene is used in a wider range of fields, including general distribution bases such as stores and homes. It is not easy to introduce an apparatus for melting and blocking a molded article in consideration of cost, installation place, generation of odor due to thermal decomposition of polystyrene, and the like. Further, in a polystyrene block obtained by melting with heat, there is also a problem that it is difficult to reuse as polystyrene because the molecular weight of polystyrene molecules is significantly reduced by thermal decomposition. Further, when the foamed polystyrene molded body is melted by heat, the foamed polystyrene is directly melted without being crushed, so that the melting time is considerably long.

[0005] Even in the case of dissolving using a solution for dissolving foamed polystyrene, if the temperature of the solution is low, the dissolution time is considerably increased and the efficiency is low. Since trays and containers, which are foamed polystyrene moldings, have been subjected to surface treatment, melting them with heat or simply dissolving them with a solution takes time to dissolve. Since various foreign matters may be mixed in the foamed polystyrene molded article, if impurities such as dust and dirt are mixed in when the foamed polystyrene is melted for recycling, the quality of the foamed polystyrene deteriorates. When the foamed polystyrene molded article is treated and reused, it is preferable to treat it with as little energy as possible.

[0006] Such expanded polystyrene is being subjected to a treatment of dissolving and reducing the volume of so-called limonene liquid. When reducing the volume of the expanded polystyrene in this manner, for example, a cylindrical container is used.
A limonene solution is contained in a cylindrical container, and foamed polystyrene is put into the limonene solution to perform a dissolution treatment. After dissolving the expanded polystyrene, the container must be transported or transported by, for example, a truck.

[0007]

However, when the container is transported by truck as described above, the limonene solution in the container and the polystyrene dissolved by the limonene solution shake or vibrate, so that the stability of the container is increased. In the worst case, the container collapses or falls. Moreover, since the amount of limonene liquid or the like in the container is not always constant, the state in which the liquid sways or vibrates in each container is different. Therefore, the present invention solves the above problems, and when transporting a state in which a fluid such as a processing solution in which a resin is dissolved and reduced in volume is accommodated, a transport container that can reduce the vibration and vibration of the fluid in the container. It is intended to provide.

[0008]

According to a first aspect of the present invention, there is provided a transport container for transporting a fluid in a stored state, wherein the transport container is a swing preventing member attached to the lid member. The swing preventing member that is disposed in an internal space that accommodates the fluid with the opening closed by the lid member and that prevents the fluid from swinging during conveyance. It is a transport container. According to the first aspect, the lid member closes the opening of the transport container so that the opening can be opened and closed. The swing preventing member is attached to the lid member, and the swing preventing member is arranged in the internal space for accommodating the fluid with the opening of the transport container closed by the lid member. The swing prevention member prevents the fluid from shaking during transportation. Accordingly, when the transport container is transported, the fluid in the transport container is less likely to sway or vibrate, and the sway or vibration of the fluid can be reduced. Thereby, in a state where the transport container is transported, the stability of the transport container is improved, and it is possible to prevent the collapse and fall of the load.

According to a second aspect of the present invention, in the transport container according to the first aspect, a fixing portion for fixing the lid member near the opening of the transport container is provided.

According to a third aspect of the present invention, in the transport container according to the first aspect, the transport container has the cylindrical internal space, and the lid member has a disk shape.

According to a fourth aspect of the present invention, in the transport container according to the first aspect, the swing preventing member is fixed to a support member of the lid member.

According to a fifth aspect of the present invention, in the transport container according to the first aspect, the swing preventing member is directly fixed to an inner surface of the lid member.

According to a sixth aspect of the present invention, in the transport container according to the first aspect, the fluid is obtained by dissolving a resin using a processing liquid and reducing the volume.

According to a seventh aspect of the present invention, in the transport container according to the sixth aspect, the resin is a polystyrene resin.

The structure of the holding section 12 will be described. The holding section 12 has a main body 50 and a container mounting section 52. The holding portion 12 is made of, for example, metal, for example, iron, stainless steel, or plastic, for example, acrylic. The main body 50 and the container mounting part 52 are integrally formed.
For example, the main body 50 is a cylindrical member, and the container mounting portion 52 is a ring-shaped or disk-shaped member. The diameter of the container mounting portion 52 is set to be larger than the diameter of the main body 50, and a plurality of grooves 54, 56, 58 are formed on the lower surface side of the portion of the container mounting portion 52 protruding from the main body 50. . These grooves 54, 56 and 58 are circular grooves formed concentrically around a shaft 60 on which the crushing blade 16 is mounted. These grooves 54, 56, 58
Although three are formed in the illustrated example, the number is not limited to this, and may be two or four or more.

The body 20 of the container is made of metal, for example iron, stainless steel or plastic, for example high density polyethylene. As shown in FIG. 1, the container body 20 is a cylindrical member having an opening 21 at the top and a bottom 22 at the bottom. The upper edge 24 of the container 20 can be removably fitted into any one of the grooves 54, 56, 58. In the example of FIG. 5, the container 20 having the smallest size is prepared, and the edge 24 of the container 20 is detachably fitted into the groove 58 having the smallest diameter. Thereby, the container mounting portion 52 closes the opening 21 of the main body 20. As described above, the container mounting portion 52 can be selectively fitted and mounted according to the size of the opening of the main body 20.

A driving section 14 is provided on the holding section 12 shown in FIGS. The drive unit 14 has a motor 14A and a speed reducer 14B, and the rotation of the motor 14A is transmitted to the shaft 60 after being reduced by the speed reducer 14B. The shaft 60 is rotatably supported by a bearing 64 at the center of the container mounting portion 52, and the crushing blade 16 and the stirring blade 18 are fixed to the lower portion of the shaft 60 so that the crushing blade 16 and the stirring blade 18 can be attached and detached and moved in the Z direction and positioned. ing. That is, the crushing blade 16
The stirring blade 18 can be moved and positioned along the axis 60 along the axis 60 in accordance with the size of the container and the capacity of the processing liquid 30 to be positioned and fixed. For example, the crushing blade 16 can be moved and positioned in the Z direction by loosening the screw 16A. Also, the stirring blade 18 can be moved and positioned in the Z direction by loosening the screw 18A.

The motor 14A is connected to the control unit 100. The control unit 100 is connected to the switch 101. The control unit 100 operates the motor 14A by turning on the switch 101. The motor 14A can arbitrarily set its operation time according to a command from the control unit 100, and can repeat forward and reverse rotations of the shaft 60 or perform only forward rotation or only reverse rotation. it can.

On the upper surface 70 of the holding portion 12, a resin inlet 74 is provided. The resin inlet 74 is formed by a receiving portion 76 and a lid 78. By providing the receiving portion 76 and the lid 78, the resin 40 to be processed can be more reliably guided into the main body 20. The cover 78 is opened by the operator operating the handle 80 for taking in and out in the X direction, as shown in FIG. 4 and FIG. The mouth 74 can be opened and closed. When the processing target resin 40 is to be charged into the main body 20 from the input port 74, the lid 78 is opened.
In the case of dissolving and reducing the volume of 0 using the processing liquid 30, the lid 78 is closed as shown by the broken line in FIG. Accordingly, it is possible to completely prevent impurities such as dust and dirt from entering the main body 20 from the input port 74 from the outside.

The container mounting section 52 of the holding section 12 preferably holds a filter 90. This filter 90
Is preferably detachably attached to the lower surface of the container mounting portion 52. The filter 90 has a shaft 60
And a cylindrical basket, for example. The filter 90 is a mesh filter, and is configured to remove impurities such as dust and dust attached to the processing target resin 40 and to prevent impurities from being transferred to the processing liquid side in the container 20. You can do it. The diameter of the filter 90 is set smaller than the diameter of the smallest main body 20.

The crushing blade 16 crushes the resin 40 to be processed, which is charged into the processing liquid 30 and located in the filter 90, into a smaller resin material 41. By crushing the resin 40 to be processed into finer resin objects 41 in this manner, the processing of dissolving and reducing the volume of the resin objects 41 by the processing liquid 30 can be hastened. In addition, stirring blade 18
By stirring the crushed resin material 41 and the treatment liquid 30 together, the process of dissolving and reducing the volume of the resin material 41 can be further accelerated. The stirring blade 18 is not always necessary and can be set arbitrarily. The main body 20 has a capacity of, for example, 20 liters to 200 liters. As described above, the main body 20 may be made of metal, plastic, or the like. For example, a drum can or the like can be employed.

Next, the operation of the resin processing apparatus 10 will be described. For example, when the smallest container 20 is prepared as shown in FIGS. 4 and 5,
Those skilled in the art will recognize that the container mounting portion 5
The second innermost groove 58 is fitted. The main body 20 contains a predetermined amount of a processing liquid 30 which is a limonene liquid. The filter 90 is detachably attached to the lower surface side of the container attaching section 52 in advance by an attaching section 99 shown in FIG.

The operator opens the cover 78 to open the input port 74, and inputs a plurality of resins 40 to be processed. The resin 40 to be processed is a used tray made of, for example, styrene foam. When the resin 40 to be processed is charged, the receiving portion 76 is provided, so that the resin 40 to be processed passes between the receiving portion 76 and the lid 78 and is surely inserted into the container 20 through the input port 74. I can guide you to In this case, the resin 40 to be treated passes through the hole 53 of the
It is thrown in.

When the operator presses the switch 101, the control unit 100 activates the motor 14A of the drive unit 14, and the shaft 60 repeats, for example, normal rotation and reverse rotation. As a result, the crushing blade 16 and the stirring blade 18 repeat normal rotation and reverse rotation. Therefore, the injected resin 40 to be treated is
The crushing blade 16 crushes the resin material 41 into finer pieces.
Although the crushing blade 16 also has a function of stirring the processing liquid 30 and the resin material 41, by further providing the stirring blade 18, the resin material 41 and the processing liquid 30 are stirred more reliably and quickly. As a result, the resin material 41 is efficiently stirred by the treatment liquid 30, so that the dissolution rate is increased and the volume reduction time is shortened.

Since the crushing blade 16 and the stirring blade 18 can be positioned by moving along the axis 60 in the Z direction, the processing liquid 3
Even if the liquid level of 0 rises or falls, the volume reduction processing of the resin material 41 can be performed efficiently. In this manner, the dissolved resin material 41 contained in the processing liquid (also referred to as a solution) 30
Reaches the prescribed concentration, the resin processing apparatus 10 is
Remove from 0. In addition, the processing liquid which is a solvent may be citrus limonene and alcohol-containing limonene.

As described above, the processing solution 30 in the main body 20 dissolves and reduces the volume of the resin 40 and processes the resin. When the concentration reaches a predetermined concentration, the processing for reducing the volume of the resin 40 ends. Thereafter, the resin processing apparatus 10 is removed from the opening 21 of the main body 20.

Next, as shown in FIG. 1 and FIG.
04 closes the opening 21 of the main body 20. And fixed part 1
30 securely fixes the lid member 104 to the main body 20 side. In this state, the anti-sway member contains the processing liquid 30 in which the resin is dissolved.
A disk 142, 1 of the swing prevention member 120 at a position below A
43 is located.

Then, the transport container 10 in the state of FIG.
0 is loaded on a transport medium F, for example, a truck, a ship, a train, or the like, and transported or transported to a recycling plant for a predetermined purpose. At this time, the transfer container 100 is shaken, but the shaking or vibration generated in the dissolved processing liquid 30 in the transfer container 100 is as small as possible because the anti-sway member 120 is located in the processing liquid 30. Can be prevented. Therefore, it is possible to easily and safely prevent the transport container 100 from falling over the transport medium F in FIG. 1 or from becoming unstable.

As shown in FIG. 3, since the holes 142 are formed in the disks 142 and 143, the processing liquid 30 shown in FIG. Even when the processing liquid 30 is generated, an appropriate amount of the processing liquid can be released from the hole 144, so that the processing liquid 30 can be prevented from shaking or vibration as a whole. Conventionally, when the amount of the processing liquid contained in the transfer container 100 is small, the vibration is increased by resonance. However, the disks 142 and 143 of the vibration preventing member 120 are located in the processing liquid. Therefore, such a phenomenon can be prevented, and the collapse and fall of the transport container 100 can be completely prevented. In addition, since the holes 144 are formed in the disks 142 and 143, even if the processing liquid in the container undergoes a sudden change, the holes 144 of the disks 142 and 143 allow the disk 142 to release an appropriate amount of the processing liquid. , 143 can stabilize the processing liquid.

Next, another embodiment of the swing preventing member of the present invention will be described. In the embodiment of FIG.

3, a circular net 3144 is provided, for example. The embodiment of FIG. 9 is slightly different from the embodiments described above, in which a support member 140 is provided inside the lid member 104. An auxiliary member 140C is fixed to the tip of the support member 140 in a direction orthogonal to the axial direction. The auxiliary member 140C is provided with, for example, four plate-shaped members 4000. These plate-shaped members 40
00 and the auxiliary member 140C constitute the swing prevention member 120.

In the embodiment shown in FIG. 10, a plurality of plate members 5000 are provided directly in parallel with the inner bottom surface of the lid member 104. These plate members 5000 constitute the swing prevention member 120. Each plate member 5000 has, for example, a circular hole 5144 formed therein, and the plate member 5000 is provided in parallel along the axial direction of the lid member 104. The plate member 5000 of FIG. 10 is provided on the inner bottom surface 104N of the lid member 104 as shown in FIG. 11, but in the embodiments of FIGS.
